摘要: A multi-layered guide wire that uses separate layers to achieve desired guide wire characteristics. Each of the layers may enhance one or more of the desired guide wire characteristics, with the combination of layers providing the desired combination of guide wire characteristics. Each of the layers may be provided over the entire guide wire, or only over selected portions of the guide wire. Further, selected layers may be co-extruded over the guide wire, which may reduce the manufacturing costs associated therewith.

摘要: For achieving, e.g., an improved electrophysiology catheter for examination of the heart, or a catheter accessing the brain, the invention, in one aspect, features an elongated wound wire coil extending through the hollow catheter body of a steerable catheter. The coil is constructed and arranged to enable the catheter body to withstand reactive compressive load without distortion during application of tension on the pull wire and to transmit torque from the proximal to the distal tip portion of the catheter to enhance fidelity of rotational positioning of the distal tip in response to rotational orientation of the proximal portion of the catheter. The coil is shown in frictional torque-transmitting relationship with the interior of the hollow shaft substantially along the common length of the catheter body when the catheter is bent. Steerable catheters with augmented throw for one-handed operation and important improvements in construction features are also shown.
